I am sure that most of us will love to have personal album on iPhone which no one can access without you permission. I got new app Secure Album which allows to copy photos and videos from the photo library into your personal albums. Just sign up to create an account in this app and create a personal album. You can create as many albums you want and copy the stills/videos from the photo library. Try this App......! iTunes Link : http://itunes.apple.com/in/app/secure-album-photos-videos/id414002056?mt=8#
I'm always concerned with this kind of stuffs. What if the devs have secret access to all those information?
You have to trust them. Apple has a killswitch for every Apple device, and they've never used it. If you're paranoid like me, jailbreak and install FirewalliP. It tracks all connections to the internet from your device and gives you the option to block them.
